Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or/and" as used herein includes any and all combinations of one or more of the associated listed items.
Some embodiments of the application are described in detail. The following embodiments and features of the embodiments may be combined with each other without collision.
Electronic devices based on MEMS technology (hereinafter referred to as MEMS devices), such as accelerometers, gyroscopes, pressure sensors, microphones, magnetometers, etc., have been widely used in mobile terminal products such as various mobile phones, tablet computers, notebook computers, electronic watches, electronic bracelets, VR glasses, etc. Stability of the mechanical structure is a key performance parameter of MEMS devices, and the primary failure of MEMS devices is also mainly due to mechanical structural failure. In order to avoid the reliability problem of the MEMS device from affecting the user experience, the risk of machine withdrawal is generated. When the mobile terminal is introduced into the MEMS device, a plurality of reliability tests are required, and the mobile terminal can be formally put into use only when the test result reaches the standard.
Reliability testing introduced by MEMS devices generally involves:
(1) The reliability test of the MEMS device monomer is used for testing the self structural reliability of the MEMS device;
(2) And (3) complete machine drop test, namely testing drop reliability of the MEMS device assembled in the whole. For example, the reliability of MEMS devices is verified by simulating severe use scenes in daily life through a roller drop and directional drop test machine.
In addition, in the reliability test process of the whole machine, when the MEMS device in the whole machine fails, the equivalent reliability test is required to be repeated in a large batch to reproduce the failure of the MEMS device, so that the risk of mass production is avoided.
For the whole machine drop test, if a mobile terminal whole machine is adopted, the whole machine is seriously damaged after the test is finished, and the mobile terminal whole machine cannot be normally used, so that the test cost is extremely high.
Some test schemes are to load MEMS devices by a special test device for complete machine drop test. However, experiments show that the test results of some known test devices have great difference from the test results obtained by adopting a real mobile terminal, so that certain problems exist in the effectiveness of the test results of the known test devices, and the test results are difficult to accurately evaluate the reliability of the whole machine of the MEMS device, so that the test results have lower value and are difficult to be used for guiding the arrangement of the MEMS device.
That is, the known technology has a problem that it is difficult to combine the test cost and the validity of the test result.
Based on this, this embodiment provides a new mobile terminal electronic device testing apparatus, a mobile terminal electronic device testing system, and a mobile terminal electronic device testing method, which have the advantages of low testing cost and high validity of testing results, and will be described in the following exemplary embodiments.
Fig. 1 to 9 show a mobile terminal electronic device testing apparatus 110 (hereinafter referred to simply as a testing apparatus 110) of the present embodiment.
Fig. 1 and 2 are three-dimensional views of a test device 110 from different perspectives, respectively. Fig. 3 and 4 are two expanded views of the test device 110, respectively.
Referring to fig. 1 and 2, the present embodiment provides a testing apparatus 110, where an electronic device 310 for testing is a MEMS device 310a, and a mobile terminal to which the MEMS device 310a is applied is a mobile phone. As shown, the test device 110 has the same or similar physical dimensions as a cell phone.
Referring to fig. 3,4 and 5 in combination, the test device 110 provided in this embodiment includes a housing 11, a carrier plate 12, a drive control board 13 and a battery 14. The carrier plate 12, the drive control board 13, and the battery 14 are mounted to the housing 11, respectively. The battery 14 may be a lithium battery or other type of battery.
The carrier 12 has a plurality of mounting locations W1 for mounting the electronic devices 310, and the electronic devices 310 are mounted on the mounting locations W1 in use. The driving control board 13 is electrically connected to the carrier board 12, and is used for driving the electronic device 310 installed at the installation position W1, so that the electronic device 310 is in an operation state and collecting relevant data of the electronic device 310 in the operation state. The battery 14 is used to power the drive control board 13 and the carrier plate 12.
The use method of the mobile terminal electronic device testing apparatus 110 in this embodiment is that the electronic device 310 mounted on the carrier plate 12 is driven by the driving control board 13, so that the electronic device 310 is in an operation state; the test device 110 is then subjected to a desired test, such as a drop reliability test; during testing, the relevant data of the electronic device 310 in the running state is collected and displayed by the drive control board 13 or transmitted to a monitoring device (such as a computer or a mobile phone loaded with monitoring software). Optionally, the monitoring device may also send control instructions to the test apparatus 110 to control the electronics 310 to set the desired operation.
The test device 110 is adopted to replace an actual mobile terminal product (such as a mobile phone) with higher price for testing, so that the cost can be remarkably reduced. Meanwhile, in the testing device 110, the battery 14 connected to the housing 11 can simulate the weight and space occupation of the battery structure of an actual mobile terminal product, and can also be used as a power supply for supplying power to the operation of the electronic device 310, so that the electronic device 310 can be tested in an electrified manner, and the battery is consistent with the actual use situation of the electronic device 310 in the mobile terminal, thereby ensuring the validity of data. Some of the known testing techniques fail to operate the MEMS device 310a in a live state during the testing process, and the device function needs to be verified again in a live state after the testing process is completed. The test cannot reproduce the live working use scene in daily life, and the validity of the test data is weak.
In addition, the testing device 110 is powered by the built-in battery 14, and a cable connected with an external power supply is not required to be additionally arranged, so that the testing result is not affected.
In addition, the electronic device 310 is mounted on the mounting position W1 of the carrier 12, so that the situation that the electronic device 310 is mounted on the motherboard of the mobile terminal in the mobile terminal can be simulated, and the validity of the test result is ensured. For example, the MEMS device 310a is mounted on the motherboard of the mobile terminal in such a manner that the pins of the MEMS device 310a are soldered to pads on the motherboard, and the pads are also provided on the carrier board 12 of the test apparatus 110 for soldering the MEMS device 310a to mechanically fix the MEMS device 310a and to supply power to the MEMS device 310 a.
The structure of the housing 11 in the present embodiment may be provided as needed, for example, as illustrated, and the housing 11 includes a center 15, a first cover 16, and a second cover 17. The first cover plate 16 is connected with the middle frame 15 through a plurality of screws 18a, and the second cover plate 17 is connected with the middle frame 15 through a plurality of screws 18 b. The middle frame 15 includes a frame plate 19 and a surrounding wall 20, the surrounding wall 20 surrounds the periphery of the frame plate 19, the surrounding wall 20 and the frame plate 19 surround a first space Q1 and a second space Q2 located at two sides of the frame plate 19, the first cover plate 16 covers the first space Q1, and the second cover plate 17 covers the second space Q2. The structure accords with the basic structure of at least part of mobile phones, and is beneficial to simulating actual mobile phones. The first cover plate 16 and the second cover plate 17 are detachable to facilitate opening of the first space Q1 and the second space Q2. The housing 11 may be made of a metal material (e.g., stainless steel, aluminum alloy, etc.) so as to have high structural strength, which is advantageous for performing a plurality of tests such as drop tests without damage.
In this embodiment, optionally, the first cover plate 16 and/or the second cover plate 17 are provided with a weight-reducing slot C1, and the frame plate 19 is provided with a weight-reducing hole K1, so that the overall weight of the testing device 110 can be adjusted to be equivalent to the weight of an actual mobile terminal (such as a mobile phone) through the appropriate weight-reducing slot C1 and the weight-reducing hole K1, and the degree of coincidence between the testing result and the testing result of the actual mobile terminal is improved.
The arrangement positions of the carrier plate 12, the drive control board 13, and the battery 14 on the housing 11 may be set as desired, for example, the drive control board 13 and the battery 14 are connected to the center 15 and located in the first space Q1, respectively, and the battery 14 is electrically connected to the drive control board 13 for supplying power to the drive control board 13. The carrier plate 12 is connected to the middle frame 15 and located in the second space Q2, and the drive control board 13 and the carrier plate 12 may be electrically connected through a flexible circuit board 21 (Flexible Printed Circuit, FPC), so as to implement communication between the drive control board 13 and the carrier plate 12, and facilitate the battery 14 to supply power to the carrier plate 12 through the drive control board 13. Optionally, the frame plate 19 is provided with a via hole K2, the via hole K2 is communicated with the first space Q1 and the second space Q2, the flexible circuit board 21 passes through the via hole K2, one end of the flexible circuit board extends into the first space Q1 to be connected with the drive control board 13, and the other end of the flexible circuit board extends into the second space Q2 to be connected with the carrier plate 12. Optionally, the drive control board 13 is provided with a first connecting seat 22, the carrier board 12 is provided with a second connecting seat 23, the first connecting seat 22 and the second connecting seat 23 are all FPC seats adapted to the flexible circuit board 21, one end of the flexible circuit board 21 is plugged into the first connecting seat 22, and the other end of the flexible circuit board is plugged into the second connecting seat 23, so that communication and power supply of the drive circuit board and the carrier board 12 are realized.
Referring again to fig. 3 and 4, optionally, a protective foam 24 is disposed on a side of the second cover 17 facing the second space Q2, and the protective foam 24 includes at least an area corresponding to the carrier plate 12. The side of the first cover plate 16 facing the first space Q1 is provided with a protective foam 24, the protective foam 24 being located in a region corresponding to the battery 14 and/or the drive control board 13, only the protective foam 24 corresponding to the region of the battery 14 being shown in fig. 4. By properly arranging the protective foam 24, the structures of the carrier plate 12, the drive control board 13, the battery 14 and the like can be protected, and the possibility of damage in the test (particularly drop test) can be reduced. For other components of the test device 110, such as the flexible circuit board 21, a protective foam protection may also be provided.
The number of electronic devices 310 may be one or more.
In this embodiment, the carrier 12 is provided with M groups of mounting positions W1, each group of mounting positions W1 includes N mounting positions W1, and m×n electronic devices 310 can be mounted, where M is an integer greater than 1, and N is an integer greater than 1. In this embodiment, the carrier 12 can mount the mxn electronic devices 310 at a time, so that the test of the mxn electronic devices 310 can be implemented at most once, and the test efficiency is improved. For example, in fig. 6, m=8 and n=8, and a total of 64 electronic devices 310 are arranged in a matrix at different positions of the carrier board 12, so that the test of 64 electronic devices 310 can be achieved at a time. Of course, it is also permissible to perform the test without mounting the electronic devices 310 at the partial mounting site W1, i.e., test less than 64 electronic devices 310 at a time. The electronics 310 may be integrated on the carrier plate 12 in a removable manner (e.g., soldering) for connection to circuitry on the carrier plate 12. For the electronic device 310 with normal functions after the test, the electronic device can be detached from the carrier plate 12 for reuse, so that the test cost is reduced. Also, the carrier 12 is detachably connected to the housing 11, so that different carriers 12 (e.g. carriers 12 with different sizes) can be replaced to simulate the electronic devices 310 on different motherboards of different mobile terminals. In addition, the electronic devices 310 are respectively arranged at different positions of the carrier plate 12, so that the performance of mounting the electronic devices 310 at different positions of the carrier plate 12 can be tested simultaneously while the testing efficiency is improved, and the suggestion of selecting the design of the mounting positions of the electronic devices 310 on the carrier plate 12 can be given. For example, if the test results indicate that the electronic device 310 located near the four corners of the carrier plate 12 performs best in combination in various tests (e.g., drop tests, etc.), the placement of the electronic device 310 on a circuit board (e.g., motherboard) prioritizes the locations near the four corners in the design of the mobile terminal. Alternatively, the material, size and connection structure of the carrier 12 may be referred to as a circuit board (e.g. motherboard) design of the actual electronic device 310 on the mobile terminal. For example, when the electronic device 310 is a MEMS device 310a mounted on a mobile phone motherboard, the mechanical structure of the corresponding carrier 12 may be modeled as a motherboard design, and is made of a printed circuit board identical to the motherboard material, and the m×n mounting locations W1 include all possible design positions of the MEMS device 310a, so that a test result of mounting the MEMS device 310a at each possible design position can be obtained in one test, and the test result can be used to guide the design position selection of the MEMS device 310 a. Of course, the specific circuit of the carrier plate 12 can be designed according to the operation requirement of the testing device 110, which has a slight influence on the mechanical performance of the MEMS device 310a and a small influence on the testing result.
In this embodiment, the mxn electronic devices 310 on the carrier board 12 can communicate with the drive control board 13 through the IIC bus 25 (Inter-INTEGRATED CIRCUIT BUS, serial communication bus). Through IIC communication, individual control of m×n MEMS devices 310a having the same address can be achieved using one IIC bus 25.
For example, as shown in fig. 5, the carrier board 12 is further provided with M IIC switches 26, and each set of mounting positions W1 is configured with one IIC switch 26 and is electrically connected to the corresponding IIC switch 26, where the IIC switch 26 functions to gate and close IIC communications. The M IIC switches 26 are electrically connected to the second connection base 23, respectively. The devices of the carrier plate 12 may be arranged as desired, for example, in one embodiment shown in fig. 6, the middle region of the carrier plate 12 is provided with 64 MEMS devices 310a distributed in a matrix; 4 IIC switches 26 (8 IIC switches 26 in total) are respectively arranged on two sides of the carrier plate 12, and each IIC switch 26 is respectively and electrically connected with 8 MEMS devices 310a nearby; the peripheral area of the carrier plate 12 is provided with a plurality of screw holes K31, which is convenient for the fixed installation of the carrier plate 12 on the shell 11. The connection of the carrier plate 12 to the housing 11 may emulate the connection of the MEMS device 310a to the motherboard in an actual mobile terminal, for example, the placement and number of screw holes K31 of the carrier plate 12 may be the same, substantially the same or equivalent to the screw holes on the motherboard.
Referring again to fig. 5, the drive control board 13 is provided with a micro control unit 27 (Microcontroller Unit, MCU), and the micro control unit 27 is connected to the mxn electronic devices 310 through IIC communication and is capable of individually controlling and monitoring the operation of each electronic device 310. Optionally, the drive control board 13 is further provided with a level conversion unit 28, and the micro control unit 27 is communicatively connected to the level conversion unit 28, and the level conversion unit 28 is electrically connected to the first connection base 22, and is communicatively connected to the M IIC switches 26 through the flexible circuit board 21, so as to implement IIC communication between the drive control board 13 and each electronic device 310. Referring to fig. 7, the drive control board 13 in this embodiment may be an ESP32 series chip.
Referring to fig. 8 and 9, in the present embodiment, alternatively, the surface of the frame plate 19 on the side facing the first space Q1 has adjacent first and second regions 29 and 30, and the drive control plate 13 is mounted to the first region 29; the second region 30 is concave inward to form a battery compartment 31. Referring to fig. 7 and 4 in combination, the battery 14 is mounted to the battery compartment 31 and is electrically connected to the drive control board 13 at the interface of the first region 29 and the second region 30. Optionally, a pressing plate 32 is disposed at the junction between the first area 29 and the second area 30, where the pressing plate 32 is used to press the connection between the battery 14 and the drive control board 13, for example, press the positive plate 33 and the negative plate 34 of the battery 14 at the two power pins 35a,35b of the drive control board 13, so as to achieve reliable electrical connection between the battery 14 and the drive control board 13. The battery 14 and the drive control Board 13 may be connected by a Board To Board (BTB) connector, and the platen 32 may be a BTB connector platen. Alternatively, the drive control plate 13 is provided with opposite first and second connecting edges 36 and 37, the first connecting edge 36 corresponding to the pressure plate 32 and being fixed to the frame plate 19 together with the pressure plate 32 by the screw 18d, the second connecting edge 37 being screw-connected to the frame plate 19. The drive control board 13 is provided with screw holes K32 at the first connecting side 36 and the second connecting side 37, respectively, for fixed mounting of the drive control board 13.
In this embodiment, the via hole K2 on the frame plate 19 is located in the first area 29, and the through hole K4 is formed in the position of the drive control board 13 corresponding to the via hole K2, so as to allow the flexible circuit board 21 located outside the drive control board 13 to pass through the drive control board 13 to enter the second space Q2 through the via hole K2.
Referring again to fig. 5, in this embodiment, the drive control board 13 is provided with circuits and devices for charging and discharging and firmware burning, such as shown in fig. 5, in addition to the foregoing micro control unit 27, level conversion unit 28 and first connection base 22, and the drive control board 13 is further provided with a battery charging and discharging unit 38, a USB interface 39 and a transfer interface 40.
Wherein, the battery 14 is electrically connected with the battery charging and discharging unit 38, and the battery charging and discharging unit 38 is electrically connected with the micro-control unit 27 for supplying power to the micro-control unit 27. The battery charge and discharge unit 38 is electrically connected to the first connection pad 22 and supplies power to the respective electronic devices 310 through the flexible circuit board 21, the second connection pad 23, and the IIC switch 26. The battery charge and discharge unit 38 is electrically connected to the level shift unit 28 for supplying power to the level shift unit 28. In this way, the battery 14 can supply power to the micro control unit 27 and the level shift unit 28 of the drive control board 13 and the electronics 310 of the carrier board 12, respectively.
To adapt to the difference of the input voltages required by different devices, the battery charging and discharging unit 38 includes a charging and discharging chip 41, a first DC-DC converting unit 42, and a second DC-DC converting unit 43, where the first DC-DC converting unit 42 and the second DC-DC converting unit 43 are electrically connected to the charging and discharging chip 41, respectively. The first DC-DC conversion unit 42 is electrically connected to the micro control unit 27 for supplying power to the micro control unit 27; the second DC-DC conversion unit 43 is electrically connected to the first connection base 22 for supplying power to the electronic devices 310 on the carrier board 12 through the flexible circuit board 21, and the second DC-DC conversion unit 43 is electrically connected to the level conversion unit 28 for supplying power to the level conversion unit 28; the micro control unit 27 is electrically connected to the second DC-DC conversion unit 43 for controlling the output level of the power supply circuit for supplying power to the respective electronic devices 310 by the second DC-DC conversion unit 43. For example, in some embodiments, the output voltage of the first DC-DC conversion unit 42 to the micro control unit 27 is 3.3V, the output voltage of the second DC-DC conversion unit 43 to the carrier plate 12 is 1.8V, and the output voltage of the second DC-DC conversion unit 43 to the level conversion unit 28 is 3.3V.
The USB interface 39 may be a Type-C interface, and the USB interface 39 is electrically connected to the battery charging/discharging unit 38, and is configured to charge the battery 14 through the battery charging/discharging unit 38, where the charging voltage may be 5V. Meanwhile, the USB interface 39 is communicatively connected to the micro-control unit 27 through a transfer interface 40 (e.g., a USB-to-serial interface) for burning test firmware into the micro-control unit 27.

Alternatively, the drop test includes a surface drop or corner drop of the test device 110, and the associated data includes a drop acceleration of the electronic device 310.
The surface drop refers to a drop mode in which the test device 110 after the electronic device 310 is mounted falls on the horizontal drop surface P0 from a set height (e.g., 1 m) in a downward posture of one of six surfaces, and fig. 17 and 18 show a bottom surface P1 drop mode and a left side surface P2 drop mode of the test device 110, and other surface drop modes and the like.
The corner drop refers to a drop mode in which the test device 110 after the electronic device 310 is mounted is dropped from a set height (e.g., 1 m) in a posture in which one of four corners is downward on a horizontal drop plane P0, and fig. 19 and 20 show a mode in which two different corners of the test device 110 are dropped.

If the maximum relative displacement is less than the initial spacing L1, it indicates that there is no risk of the MEMS device 310a striking the first cover plate 16 during a drop.
Referring to fig. 22 and 23, for the mounting manner in which the carrier plate 12 is fixed to the frame plate 19 with a round screw 18c at the outer periphery, the displacement of the MEMS device 310a at the intermediate position is generally maximized.

Referring to fig. 25, the practical simulation also shows that, during the falling process, both the carrier plate 12 and the first cover plate 16 are bent and deformed, but the MEMS device 310a does not contact the opposite first cover plate 16, which verifies that the testing device 110 itself has higher falling reliability.
In this embodiment, the dropping step b) is used as the simulation of the possibility of the MEMS device 310a of the testing device 110 and the shell collision, so that the reliability of the testing device 110 itself can be well determined, the possibility of the collision damage between the MEMS device 310a and the first cover plate 16 in the test can be eliminated, and the reliability of the test result is further ensured.
C) Referring to fig. 26 and 27, the surface falling is performed in a manner that the carrier plate 12 is parallel to the falling surface P0 and the electronic device 310 on the carrier plate 12 faces the falling surface P0, in this embodiment, the surface falling of the second cover plate 17 faces the falling surface, the maximum deflection of the electronic device 310 in the falling process, that is, the maximum displacement of the electronic device 310 under the driving of the deformation of the carrier plate 12 is calculated, if the maximum deflection is smaller than the set deflection value, the verification is passed, otherwise, the verification is not passed; as shown in fig. 26, 64 MEMS devices 310a on the testing device 110, the testing device 110 itself falls the reliability verification test to see fig. 27, the peak of the falling displacement is as shown in fig. 28 and 29, the maximum deflection (the maximum displacement in the thickness direction) of the electronic device 310 presents a nearly centrosymmetric distribution; the maximum deflection of the middle part is 1.72906, the maximum value meets the requirements, the edge is constrained by screw connection, and the maximum displacement is about 1/3 of the middle part.
D) Referring to fig. 30, the surface falling is performed in such a way that the driving control board 13 is parallel to the falling surface P0 and the driving control board 13 faces the falling surface P0, in this embodiment, the surface of the first cover board 16 facing the falling surface P0 falls, if no collision exists between the device on the driving control board 13 and the opposite side structure of the driving control board 13, the verification is passed, otherwise the verification is not passed;
Through simulation, referring to fig. 30, the driving control board 13 and the opposite side first cover board 16 have no risk of collision damage, and especially when the protection foam protection is arranged between the shielding cover of the driving control board 13 and the first cover board 16, the driving control board 13 can be kept in normal use in the testing process, and no risk of collision damage is caused.
E) Referring to fig. 31 and 32, the surface falling is performed in such a manner that the battery 14 is parallel to the falling surface P0 (including the surface falling of the first cover plate 16 facing the falling surface P0 and the surface falling of the second cover plate 17 facing the falling surface P0), if the deformation amount of the battery 14 meets the set value and the battery 14 and the opposite side structure have no risk of collision failure, the verification is passed, otherwise the verification is not passed;

Referring to fig. 33-36, in verification, 64 MEMS devices 310a on carrier plate 12 exhibit a high center, low periphery effect in terms of drop acceleration peak. The middle part has low rigidity, the peripheral rigidity is high, and the acceleration frequency of the middle part is lower than that of the peripheral part; therefore, after the peak value is converted into the peak value within 0.1ms under the same time domain amplitude, the middle acceleration peak value is higher than four weeks. Meets the set value of the severe test of the peak acceleration of the whole machine of 15000g at the highest.
After the test device 110 passes the verification of the above steps, the test device 110 is considered to have a good drop reliability, and can be preferably used for the formal power-on state drop test of the MEMS device 310 a. However, some other testing methods do not fully consider the problem of the stability and reliability of the self structure of the testing device 110, possibly introducing interference factors to the testing result, or failing to accurately determine which specific structures or positions may have a non-negligible effect on the testing result, so that a corresponding self reliability detection means cannot be given out, and thus the testing result may be greatly affected by the stability and reliability of the testing device 110, and the effectiveness of the testing result is reduced.
